2）同位语从句中的that 是连词，在句中不作成分，一般不可省略(the fact that 中的that 有时可省)；定语从句中的that既代替先行词，也在句中作成分，常可省略。
3）同位语从句的先行词多为抽象名词，定语从句的先行词既可以是抽象名词，也可是具体名词。

名词性从句
名词性从句 在句子中起名词作用的各种从句，统称为名词性从句。根据它们在句中所起的语法作用，这类从句分别称为主语从句、 1.作动词的宾语 ①大部分宾语从句直接跟在动词后： He doesn’t know where the post office is. 他不知道邮局在哪里。 ②有些宾语从句前要有间接宾语： He told me what I should read. 他已告诉我应该读些什么。 ③如果宾语从句后面有宾语补足语，要使用形式宾语it，而将从句放到补足语后面： I thought it strange that he failed to call me. ④在think, believe, suppose, expect等动词之后的宾语从句中，如果从句谓语是否定含义，则不用否定形式，而将主句谓 语动词think等变为否定形式： I don’t think you are right. *⑤在think, believe, imagine, suppose, guess, hope 等动词以及I’m afraid等后，可用so代替一个肯定的宾语从句，还可用not代替一个否定的宾语从句： E.g. --- Do you believe it will clear up? 你以为天气会转晴吗？ --- I believe so. 我认为会这样。 (--- I don’t believe so./I believe not.) 我认为不会这样。 －Do you think it’s going to rain over the weekend? －. A．I don’t believe B．I don’t believe it C．I believe not so D．I believe not －Don’t you think Jack’s health has been ruined by over drinking? －Yes, he told me himself. A．the thing B．it C．so D．the fact 2. 作介词的宾语 ①that引导的宾语从句只有在except, in, but, besides等少数介词后偶尔可能用到： Your article is all right except that it is too long. 你的文章挺好，只是太长了。 Did she say anything about how we should do the work? 关于这工作我们该怎么做她说什么没有？ *②有时在介词和其宾语从句的中间加形式宾语it; 如短语动词answer for（担保）、count on (期待)、depend on、insist on、see to(负责，确保)等后接that引导的宾语从句时，必须冠以形式宾语it。 I’ll see to it that everything is ready. 我将负责把一切准备好。 ③介词后的宾语从句不能由if引导，而要用whether. I’m counting on it that you will come.我期待着你的到来。 She’ll see to it that he goes ahead.她将确保他继续进行。 3. 作形容词的宾语 在某些形容词（如afra id“恐怕”，sure“确信”，certain“肯定”，confident“相信”等）作表语时，可接一个that引导的宾语从句（也有人认为是状语从句）： I’m afraid (that) I have made a mistake.恐怕我犯了一个错误。 表语从句 表语从句放在连系动词（如be, seem, remain等）后： The question is whether we should accept their invitation. 问题是我们是否应该接受他们的邀请。 1.when, where, why, because, how 等引导的从句作This is 和That is 的表语 时，表示具体的时间、地点、原因、方式等： This is why we put off the meeting. 这就是我们推迟会议的原因。 This is why…＝＞This is the reason why… This is where…＝＞This is the place where… This is when…＝＞This is the time when… This is how…＝＞Thi s is the way(that/in which)… 2．主语是reason时，表语从句常用that, 不用because; The reason for his absence was that he was ill。 他缺席的原因是病了。 3．as, as if, because 有时也可引导表语从句； Things were not as they seemed to be. 情况并不是看上去的那个样子。 It looks as if it is (或：were) going to rain.看起来天要下雨。 ▲注意：as if引导的表语从句有时也可用虚拟语气，表示可能性小。 主语从句 主语从句在复合句中作句子的主语。引导主语从句的词有连词that, whether, 连接代词who, what which; 连接副词when, where, how, why等。 如：1) What is needed for the space trip is careful preparation. 2) Whether wild life can be well protected is of great importance. 3) Who will go makes no difference. 1.主语从句可以直接放在句首；也可用it作形式主语，而将从句放在句末。 如：That light travels in straight lines in known to all. It’s known to all that light travels in straight lines. 众所周知，光沿直线运行。 When we shall have our sports meet is still a question.

经典英语名词性从句
名词性从句在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether，关系代词：who, what, which, whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever等。 That you don’t like him is none of my business.你不喜欢她不管我的事。 What he said is true. 他说的是真的。 Do you remember how he arrived almost at the end of the party?你记得他几乎是在宴会快结束时才到的吗？ This party's really where it's at, man! 啊，这个晚会真棒！Tell us how you fulfilled the heavy task ahead of schedule.告诉我们,你们是怎样提前完成这一艰巨任务的。 We have reason to believe that the fighting on the border may develop into a full-blown war.

英语名词性从句
